Product information

Description

ABB FH202 AC-40/0.03 is a 2-pole residual-current device (RCD) of Type AC designed for earth-leakage protection in residential and light commercial electrical installations. Rated for 40 A and 230 V at 50 Hz, it detects residual currents at 30 mA sensitivity and trips to interrupt the circuit when alternating fault currents to earth are present. The device is intended for DIN-rail mounting and features IP2X finger-protection on its front, providing basic mechanical protection against accidental contact.

Advantages

The FH202 AC-40/0.03 provides reliable protection against electric shock from alternating leakage currents and reduces the risk of fire caused by earth faults. Its 30 mA sensitivity meets common safety requirements for personal protection in living spaces. Compact two-pole design saves space in distribution boards and the product is compatible with standard DIN-rail installation practices. The IP2X rating offers front-side protection during normal operation and handling.

Suitable for

Residential distribution boards protecting general lighting and socket circuits
Small commercial or office installations with single-phase loads
Protection of circuits where detection of AC-type earth leakage is required
Retrofit or new installations using standard DIN-rail modular devices

When it may not be suitable

This Type AC RCD detects only sinusoidal alternating residual currents and will not reliably detect pulsating DC or complex fault currents produced by some electronic equipment. For circuits with devices that can generate DC leakage components (for example, certain solar inverters, EV chargers or electronic power supplies), a Type A or other appropriate RCD should be considered. The device's IP2X rating provides basic front protection but is not intended for use in environments requiring higher ingress protection.

Key specifications

Type: AC residual-current device (RCD)
Poles: 2-pole
Rated current: 40 A
Rated voltage: 230 V AC
Frequency: 50 Hz
Residual operating current: 30 mA
Tripping characteristic: instantaneous
Mounting: DIN-rail modular mounting
Front protection: IP2X (finger protection)
Weight: 0.2 kg

How to use

Install the ABB FH202 AC-40/0.03 on a standard 35 mm DIN rail inside the distribution board following applicable wiring regulations. Connect the supply and load conductors to the designated terminals, ensuring correct polarity and secure tightening of terminals. After installation, test the RCD using its test button (if present) or a qualified tester to verify proper tripping at the rated residual current. Periodic testing and visual inspection are recommended according to local electrical codes to confirm continued operation.

What to consider before purchase

Confirm the required RCD type for your installation (Type AC vs Type A) based on connected equipment
Ensure 40 A rated current is suitable for the circuits to be protected
Verify space and compatibility with your distribution board and DIN-rail layout
Check local regulations for required sensitivity (30 mA) and periodic testing intervals

Usage recommendations

Use this RCD for personal protection on general-purpose circuits and perform routine tests after installation and at regular intervals. For installations with equipment generating DC leakage or complex residual currents, select a device with an appropriate detection type.
